    I have known RMA (and Doug Ruhlin) for over 12 years, working closely with him at NRMCA. He has always been a great spokesman and friend of our industry. Through the association, he works tirelessly to provide excellent programs and tools for our industry. His desire to see our industry move forward and grow has been an integral part of driving the Operations, Environment & Safety Committee within NRMCA. Recently we contracted with RMA on a time-sensitive project, they were able to meet our needs with quality service. Their knowledge of our industry and quick feel for our company made for a very smooth project. RMA understands the challenges our industry faces and helps provide effective solutions. I highly recommend RMA and we will definitely use them as future needs arise.

    Resource Management Associates is a key influence to our environmental program. We operate several ready-mix concrete plants in 3 states, which all have unique regulations to deal with. They've assisted in everything from seeking approvals from local townships, preparing SWPPPs, environmental training for employees, and establishing environmental best practices at our concrete plants. RMA has done an excellent job of maintaining compliance with new environmental laws and regulations. By working with RMA we have been proactive and are one step ahead of any visits from environmental agencies.

    I first met Doug of RMA in 2002 when I attended an environmental course he developed for the National Ready Mixed Concrete Association. Doug’s ability to effectively communicate and explain the voluminous environmental regulations pertaining to the concrete industry is remarkable. He is truly a gifted speaker and teacher. If you are new to the industry or the environmental field, I strongly recommend participating in Doug’s courses. Since then, we’ve worked together on several projects including an NPDES permitting, and most recently, further development of the Green-Star EMS Program at NRMCA. Doug’s passion, experience, and insight are always welcomed assets on any environmental project.

    I have known Doug Ruhlin of RMA for nearly 20 years. RMA has been a leader in the environmental arena for all of that time. They're intimately versed in the key environmental issues that affect aggregates and concrete producers; they know the laws, regulations and both industries thoroughly. RMA has helped steer the formulation of new regulations and they have helped to direct industry's response to the current and new regulations - in multiple states. I would not acquire an existing operation or start a greenfield plant or quarry without consulting Doug.

    I have known RMA for many years and I greatly respect their knowledge. They've served on concrete industry committees in leadership roles and have helped develop and professionalize the concrete industry's body of knowledge with regard to environmental management and compliance. The Tennessee Concrete Association hired Doug Ruhlin of RMA to help with a revision to our NPDES Stormwater Management Plan when our statewide permit was last revised. Doug (and RMA's) work was excellent and I am happy to recommend them to others.

    After an extensive search, our firm hired RMA to educate our team on industry environmental best practices. Doug and his team were very thorough in their presentation and supporting documentation, and gave us a real world expectation of what we should be mindful of regarding reclaiming, slurry water, pH levels, permitting and other topics. I would highly recommend RMA to any company interested in understanding the important elements of environmental compliance, sustainability and those interested in positioning themselves as leaders in environmental stewardship.
